System sheathing, the roof or wall should be covered with an additional
roofing underlayment or water resistive barrier prior to installation of the
new finished roofing or cladding.
Note: In cladding systems requiring multiple layers of water -resistive barriers,
like traditional hard -coat stucco, ZIP System sheathing is intended only to
replace the first layer.
Wet Blown Cellulose Insulation
- In addition to following manufacturer installation instructions, we recommend
a maximum moisture content of the cellulose of less than 2 % measured at
the inside surface of the ZIP System panel before closing l�he wall cavity.
Secondary Coatings Iil
Do not apply secondary coatings or treatments to ZIP Syste Roof & Wall
sheathing panels with the exception of the following:
HEW approved fire resistant coatings. Fire resistant co tings must be
tested and approved by HEW for use with ZIP System panels.
Field applied water-soluble borate insecticide or fungicide treatments
applied to the non overlay side of the panel. See technicAl tip, "Termite
Treatments on ZIPS stem Roof & Wall Sheathing," Y
y g," on zipsystem.com for
more information.
Permeable laminated radiant barrier foil or paint. For a radio t barrier foil or
coating to be considered permeable, it must have an applied'permeance of
five perms or greater as tested by the ASTM E 96 wet cup s'andard. For a
radiant foil, the permeance evaluation would include any a io hesive and/or
backer used to laminate a foil. For a radiant paint/coating, the permeance
evaluation should be conducted at the applied thickness of the�paint/coating.

ZIP System® Sheathing Installation on Roofs
Overview: ZIP System Roof & Wall sheathing is composed of ZIP System panels and ZIP System seam sealing tape. ZIP System" Roof & Wall Sheathing
panels should be fully installed before the seam sealing tape is applied. In general, the ZIP System roof sheathing panels should be installed from Itt�e lowest point
on the roof to the highest. It is at the discretion of the installer whether to apply tape from the top down or from the bottom up. However, working fllom the highest
sections of the roof and working down will minimize foot traffic on the tape. The following installation steps are presented as guidelines and a general i outline of
the installation process. These are manufacturer installation recommendations— please visit zipsystem.com for a library of flashing and installation tletails. You are
fully and solely responsible for all safety requirements. Good construction and safety practices should be followed at all times. 1
Step 1.
11
- Ensure that the panel surface is dry and clean of any nails, sawdust, or+s9,
other debris or protrusions prior to installing or walking on the panels.
- After ensuring compliance with all OSHA and local code safety
guidelines, install ZIP System sheathing panels with the moisture
barrier surface facing outside. The long edge (8') should be oriented
perpendicular to the framing members, and panels should be installed
with the 4' edge seams staggered a minimum of 24".

Step 2.
- Ensure that ZIP System panels span at least three framing members and
a framing member supports the entire 4' edge of the panels.
- Fasten the ZIP System Roof & Wall sheathing panel to the framing
members with code approved fasteners spaced at the appropriate
edge and intermediate spacing. It is the responsibility of the general
contractor to verify proper fastener type and spacing prior to installation.
- Apply the fasteners 3/8" from the panel ends and corners.
I
-' An ideal installation would be where fastener heads are flush with the
panel surface. However, due to variations in materials and limitations
V
on equipment, this may be difficult to achieve in some situations. It
is not required to tape over overdriven fasteners unless the fastener
head creates a hole through the entire panel thickness. Please see

ZIP System'" Tape Installation - Roof Panel Seams
Apply ZIP System tape after all ZIP System Roof & Wall sheathing panels are fully fastened to roof -framing members. Only ZIP System tape sh iuld be used to
seal the seams of ZIP System panels. Ensure that the panel surfaces are dry and free of any nails, sawdust and other debris, or protrusions. Avoid stepping
on tape in high temperature environments. ZIP System tape is a contact tape that requires pressure for an adequate seal.
Step 1.
- Apply ZIP System tape to every vertical and horizontal panel seam. It is
at the discretion of the installer whether to apply tape from the top down
or from the bottom up. However, working from the highest sections of
the roof and working down will minimize foot traffic on the tape.
- Ensure that the tape is centered over the seam within +/- 1/2" to provide
adequate coverage and to ensure that wrinkles in the tape are minimized.
- Ensure that tape lengths are continuous across the 8' horizontal edge
of the panels. If splices are unavoidable, create an overlapping splice
of at least 3". Apply moderate pressure onto the surface of the tape to
ensure a secure bond between the panel and the tape.
- Use ZIP System tape gun or tape roller to apply pressure to the tape
and smooth out any wrinkles.
- Take special care to remove any voids and/or trapped air at splice
areas and T-joints.
(Step 2.
For valley areas of framing, we recommend you use 6" wide ZIP System
tape. This tape is wider than panel seam tape and is designed to give you
optimal protection in valley areas.
- Starting from the bottom and working your way up, apply one continuous
i
piece of 6" tape so that the center of the tape is over the valley seam.
Use the tape gun or tape roller to apply pressure to the tape to ensure
proper contact with the panel and to eliminate any wrinkles that might
I have occurred in the tape. Take special care to seat tape completely
into the valley.
Note-
1 It is important to pay extra attention to valley taping as water is
directed toward the valleys during rain events.
-' Self -adhering ice and water barriers may be required by code. ZIP
System tape is not considered a replacement for self -adhering ice
and water barriers. Therefore, when self -adhering ice and water
barriers are required, they should be installed in addition to ZIP
System tape.
